12=-4-2x-6x

12 = - 4 - 2 x - 6 x

x = - 2

Solution steps

12 = - 4 - 2 x - 6 x

Switch sides

- 4 - 2 x - 6 x = 12

Add similar elements:

- 2 x - 6 x = - 8 x

- 4 - 8 x = 12

Move

4

to the right side

- 8 x = 16

Divide both sides by

- 8

x = - 2

4 x + 2 = x + 8

8 (x + 2) = 40

x, (x - k)^{2} = k^{2} - 2 x + x^{2}

a, 5 = 2 a - b

lo g_{\frac{1}{5}} (125) = - 3
